5.6 Image processing
The Settings menu offers a unique wide range of image processing significantly improving the
data quality and the clarity of different views.
5.6.1 Gain
Due to GPR energy attenuation in concrete, some objects may appear weak or invisible. By
increasing energy through gain, the image can be improved with targets being more visible.
Figure 24: GPR ground wave's energy attenuation
GP app software provides in image processing dropdown menu an automatic gain called
“Auto-Gain” which automatically adjusts the gain and amplifies the signal to improve the image
quality. However, it is possible to adjust manually the gain with “Linear Gain” & “Time Gain
Compensation” settings.
